Leaves getting brown and dry, please help

[Monika23]

Hello,

I got this plant as a present in June 2018 and I would be grateful if someone could answer my questions about it.

First, I don't know what type of orchid is it and whether it actually is an orchid. Any ideas would be helpful (see pictures). The leaves are about 20 cm long and about 7 cm broad at the broadest point. I think that it used to have small white flowers in the summer but they got dry and fell of within couple of weeks.

There appear to be some problem with the plant, the leaves are getting brown and dry and they seem to be dying. One leave already got completely brown and fell. The stem is also brown.

I wonder what can I do to save it? how often and how much shall I water it? Does it need to be near window or far? What is the best temperature for it? I usually switch of the heater for night and during the day when I am at work, but I don't think that the temperature ever gets below about 18C.
I have been watering it a little bit about every four days. When I noticed that it has been getting brown, I started to water it every other day during the last two weeks, but it doesn't seem to help.

Also there appeared to be a little bit of mould on the soil, so I removed the top layer of soil with the mould. Is it possible that I need to buy a new soil and put it into a new pot?

I guess I should at least add some soil, but I am not sure which type of soil would be the best?

Many thanks
